This will be my first switching supply, so I want to consult with you guys before I do anything. There are a plethora of manufacturer and devices from TI and LT and it's got me a little overwhelmed.
This is what I need:
Input from 9-32 VDC
Output of 3.3V
Output current 500mA maximum
There is a potential for a lot noise on the incoming supply as it will be powered by industrial equipment with an alternator and other weird devices on it (not sure if this matters in the selection). The switcher will be powering a uC and a 900 MHz wireless radio.
I'm also a little lost on what switching frequencies I should use and am trying to find a device with a minimal amount of external support components. Can anyone help me with a device that might be nice to work with for a switching newb?
